Image formation layer 13 is arranged on the tabular surface 11A sides of bi-convex lens sheet 11.Image formation layer 13 is by transparent Resin sheet be on image forming medium 12 printing or transferred image and formed.As long as the material of image formation layer 13 can adhere to In the material of image forming medium 12, then it is not particularly limited, known coating etc. can be used.
Also, bi-convex lens sheet 11 is engaged with image forming medium 12 using the methods of bonding or bonding.It is double as inciting somebody to action The cement (bonding agent or adhesive) that convex lens sheet 11 engages with image forming medium 12, can be used can be via biconvex lens Piece 11 observes the material with the transparency of image formation layer 13.Also, it is preferred that bi-convex lens sheet 11 and image forming medium 12 The cosmetic sheet being integrally formed has flexibility.
Image formation layer 13 is made up of the 1st divided area S1 and the 2nd divided area S2 and intermediate region SM.1st subdivision Region S1 and the 2nd divided area S2 and intermediate region SM is in unit area U corresponding with cylindrical lens 15 (reference picture 4 and figure 5) 1 group is respectively provided with, and is extended along Y-direction.A side region of the 1st divided area S1 configurations in unit area U is (for example, left Side region), the 2nd divided area S2 configures another side region (for example, right side area) in unit area U.Intermediate region SM Configure the middle section between the 1st divided area S1 and the 2nd divided area S2.1st divided area S1 and the 2nd divided area S2 Formed turns on symmetrical position with the optical axis of cylindrical lens 15.
For cosmetic sheet 10, tilted to the right from the orthogonal direction (DV Fig. 2 shown in) orthogonal with image formation layer 13 Right side incline direction (DA shown in Fig. 2) observation image formation layer 13 when, only observe the 1st divided area S1.Also, it is directed to Cosmetic sheet 10, left side direction (DB shown in Fig. 2) the observation image formation layer 13 inclined to the left from orthogonal direction DV When, only observe the 2nd divided area S2.Moreover, cosmetic sheet 10 is directed to, from orthogonal direction DV during image formation layer 13, only It was observed that intermediate region SM.
In 1st divided area S1, the 1st pattern P1 shown in Fig. 3 (A) is subdivided into banding and forms image.2nd subdivision area In the S2 of domain, the 2nd pattern P2 shown in Fig. 3 (C) is subdivided into banding and forms image.In the SM of intermediate region, shown in Fig. 3 (B) Gradual change pattern PG is subdivided into banding and forms image.Specifically, the 1st pattern P1, the 2nd pattern P2 and gradual change pattern PG be such as As shown in Figure 4 in the state of banding is subdivided into, in the 1st divided area S1, the 2nd divided area S2 and intermediate region SM Image is formed respectively.
Therefore, for cosmetic sheet 10, by the way that the direction of observation of image formation layer will be observed via bi-convex lens sheet 11 along X side Right side incline direction DA, orthogonal direction DV, left side direction DB are turned to becoming successively, to observe the 1st pattern P1, gradual change successively Pattern PG and the 2nd pattern P2.
1st pattern P1 and the 2nd pattern P2 are formed by the pattern for combining different multiple shapes.In addition, here, by making Direction rotates and becomes consistent shape and be also referred to as different shapes each other.
In present embodiment, the 1st pattern P1 and the 2nd pattern P2 have been imitated carbon fiber being set to twill figure caused by twill Case.Twill is the weave for instigating the longitudinal row of carbon fiber to intersect respectively every two row with laterally row.As shown in figure 3, twill pattern In, (that is, the length of side of Y-direction is longer) the 1st rectangle R1 of lengthwise is arranged on 45 ° of direction being tilted relative to X-direction or Y-direction 1st pattern of row and the 2nd figure that (that is, the length of side of X-direction is longer) the 2nd rectangle R2 is arranged on the direction for tilting 45 ° of growing crosswise Case is by alternately repeatedly.That is, the 1st pattern P1 and the 2nd pattern P2 is the 1st pattern by the 1st rectangle R1 and the 2nd rectangle R2 compositions With the combination of the 2nd pattern.
Gradual change pattern PG is also the 1st pattern and the 2nd rectangle that the 1st rectangle R1 is arranged on the direction for tilting 45 ° in the same manner The 2nd pattern that R2 is arranged on the direction for tilting 45 ° is by pattern alternately repeatedly.
In image formation layer 13, image (also known as " gray value ") is formed with the concentration of defined gray scale width.This implementation In mode, the image formed in image formation layer 13 is netrual colour, is represented with so-called GTG (gray scale).1st pattern P1 and the 2nd pattern P2 is described using the minimum gradation value (Cmin) and maximum gradation value (Cmax) of gray scale width. Specifically, in the 1st pattern P1, the 1st rectangle R1 is equably filled with Cmin, the 2nd rectangle R2 with Cmax equably Fill.On the other hand, in the 2nd pattern P2, the 1st rectangle R1 is equably filled with Cmax, and the 2nd rectangle R2 is equal with Cmin Fill evenly.
The 1st pattern P1 and the 2nd pattern P2 each in, the 1st rectangle R1 and the 2nd rectangle R2 concentration is inverted each other.This It is due to have imitated in the twill pattern of the carbon fiber of reality, by the carbon fiber (corresponding with the 1st rectangle R1) of longitudinal direction (Y-direction) With the carbon fiber (corresponding from the 2nd rectangle R2) of transverse direction (X-direction) caused by light reflex components it is different, and concentration is observed to not Together.
Also, in the 1st pattern P1 with inverting concentration in the 2nd pattern P2.Specifically, it is minimum dense in the 1st pattern P1 Degree is that the 1st rectangle R1 turns into Cmax in the 2nd pattern P2, and the Cmax in the 1st pattern P1 is the 2nd rectangle R2 the 2nd Turn into Cmin in pattern P2.This is due to have imitated in the twill pattern of the carbon fiber of reality, and direction is dense according to the observation Degree inverts and is observed to different patterns.
Also, gray values (intermediate concentration) of the gradual change pattern PG between minimum gradation value and maximum gradation value is depicted. Specifically, in gradual change pattern PG, concentration is made in the 1st rectangle R1 and respectively periodically to occur in X direction in the 2nd rectangle R2 Change.Be not in oblique all as uniform concentration if the 1st rectangle R1 and the 2nd rectangle R2 filled with a kind of concentration The shape of line pattern., can will gradually by making the 1st rectangle R1 and the 2nd rectangle R2 concentration periodically change in X direction Become pattern PG to be set to the intermediate concentration between Cmin and Cmax and describe twill pattern.
Fig. 5 shows the 1st rectangle R1 of image formation layer 13 regional area.Between the 1st pattern P1 and the 2nd pattern P2 In the same manner, the 1st divided area S1 and the 2nd divided area S2 concentration inverts relation each other.Symbol U1~U5 represents to arrange in X direction 5 unit area U of row.
1st divided area, the length of intermediate region and the 2nd divided area and relation between them be not limited It is fixed, but be set in the present embodiment, when by the 1st divided area S1, intermediate region SM and the 2nd divided area in X-direction When S2 length is set to W1, WM and W2, meet WM ＜ W1, WM ＜ W2, W1=W2 relation.Specifically, in this implementation In mode, " W1: WM: W2=5: 2: 5 " relation is set to.
Fig. 6 (A)~Fig. 6 (E) is the chart for the gray value (concentration) for representing unit area U1~U5.Fig. 6 (A)~Fig. 6 (E) In, maximum gradation value (Cmax) is set to GH, minimum gradation value (Cmin) is set to GL.Intermediate region SM concentration GM periodically occurs between Cmax GH and Cmin GL, and along the orientation (X-direction) of cylindrical lens 15 Change.
By above structure, if making the direction of observation for cosmetic sheet 10 change in X direction, in observed figure As switched to from the 1st pattern P1 during the 2nd pattern P2 or observed image from the 2nd pattern P2 switch to the 1st pattern P1 when, see Observe the gradual change pattern PG that the intermediate concentration between the 1st pattern P1 and the 2nd pattern P2 depicts twill pattern.
As described above, in the cosmetic sheet 10 of the present invention, if changing direction of observation, observed image is anti-each other in concentration Switch between the 1st pattern P1 and the 2nd pattern P2 that turn, and the light and shade for looking like decorative pattern changes, therefore obtain third dimension. Thus, cosmetic sheet 10 can obtain and carbon fiber sheet in kind is equal or the quality more than it.
Especially, in the carbon fiber sheet of material object, when varying viewing directions, become by the light reflex components of carbon fiber Change and changed so as to the light and shade of decorative pattern, therefore the change of light and shade is not likely to produce under the less environment of light quantity, but in the present invention Cosmetic sheet 10 in, under the less environment of light quantity, can also pass through the pattern P1 of function switch the 1st of bi-convex lens sheet 11 With the 2nd pattern P2, so as to substantially there is the change of light and shade.

Moreover, the length WM of the intermediate region SM in X-direction is than the subdivisions of the 1st divided area S1 length W1 and the 2nd area Domain S2 length W2 is short, therefore observes gradual change pattern PG angular range only near orthogonal direction DV.Therefore, in observer Direction of observation when continuously changing, it was observed that gradual change pattern PG time is shorter, therefore the 1st pattern P1 and the 2nd pattern P2 is switched naturally and with the short time.
In addition, in above-mentioned 1st embodiment, the 1st pattern P1, the 2nd pattern P2 and gradual change pattern PG are set to twill figure Case, but the present invention is not limited to this, for example, it is also possible to plain weave being set to the variation as shown in Fig. 7 (A)~Fig. 7 (C) Pattern.Plain weave is to instigate the longitudinal row of carbon fiber and laterally arrange the weave alternately intersected.That is, flat-grain pattern is equivalent to will be by The 1st rectangle R1 and the 2nd rectangle R2 (reference picture 3) that the twill pattern of 1 embodiment is formed are set to substantially square Pattern.
Therefore, in the variation shown in Fig. 7 (A)~Fig. 7 (C), the 1st pattern P1, the 2nd pattern P2 and gradual change pattern PG are equal Distinguish interconnected pattern as the square T2 of the 1st square T1 and the 2nd.1st square T1 and the 2nd square T2 concentration It is identical with the 1st rectangle R1 and the 2nd rectangle R2 of the 1st embodiment concentration.
In addition, the 1st pattern P1, the 2nd pattern P2 and gradual change pattern PG are not limited to illustrate in above-mentioned 1st embodiment The 1st rectangle R1 and the 2nd rectangle R2 patterns combined, the 1st square T1 that enumerates in variation and the 2nd square T2 groups The pattern formed is closed, as long as the pattern that combination quadrilateral forms.Also, in above-mentioned 1st embodiment and variation, 1st pattern P1, the 2nd pattern P2 and gradual change pattern PG are set to the image of netrual colour, but can also be set to coloured image.
It is set in above-mentioned 1st embodiment and variation, image formation layer 13 is formed on image forming medium 12, And engage image forming medium 12 with the tabular surface 11A of bi-convex lens sheet 11, but can also be without using image forming medium 12 and on the tabular surface 11A of bi-convex lens sheet 11 directly formed image formation layer 13.
